LOL!!! Very cool! Perfect betta or shrimp tank, if you can get that undergravel filter outta there!!!! I'm sure that you could do a DIY LED....get rid of that incandescent thing....it'll turn that tank into a pot of soup from all the heat!
I've no idea what it's called, but I think "RetroCube" is fine! Though, I think it's funny that you believe 1987 to be "retro"! I was 11 years young at the time!
